JOHN H. KELLY, or STAN-TON, AND JOHN H. MERSHON, or VAN ALSTYNE, TEXAS.

Application filed December 14, 1911.

To all whom it may concern Be it known that we, J OHN H. KELLY and JOHN H. MERsHON, citizens of the United States, residing at Stanton and Van Al styne, in the counties of Martin and Gray son, respectively, and State of Texas, have invented certain new and useful 'Improvements in Blades, of which the following is a specification.

This invention has relation to weed blades adapted to be attached to a cultivator, and has for its object to provide a blade of simple structure adapted to be applied to the rear side of the pointor moldboard .of the cultivator with an edge portion which projects beyond the edge of the same.

For a full understanding of the invention reference is to be had to the following description and accompanying drawing, in which Figure 1 is a perspective view of a middle burster with the blades attached; Fig. 2 is a transverse sectional view through a moldboard and share and a blade attached there-.-

to; Fig. 3 is a horizontal sectional view of the same; Fig. 4 is an edge elevation of one form of the blade; Fig. 5 is a rear view of Corresponding and like parts are referred to .in the following description and indicated in all the views of the accompanying drawing by the same reference characters.

The blade consists of a body portion 1 having a forward cutting edge 2. At its inner end the body portion 1 merges into a shank 3 which is twisted slightly with relation to the body portion 1, the axis of the twist being approximately midway between the side edges of the shank 3. The inner end of the shank 3 terminates in an angularly disposed lug 4, and the shank 3 is provided with a perforation 5 through which a securing bolt, indicated at 6, is adapted to Specification 0f-Letters Patent.

be passed. Cleats 7 are secured to the rear side of the share, mold-board or point of the plow in the usual manner, and the shank portion 3 of the blade fits against the rear side of one of the cleats. The lug 4 extends along the edge of the cleat. When the bolt 6 is passed through the cleat, plow point and blade, the blade is securely held in position upon the cleat with its cutting edge 2 approximately horizontal when the point,

share or moldb0ard is inserted in the soil.

end of the shank 3 is angularly disposed with relation to the shank formin the lug 4. This leaves a part of the extremity of the shank in the same plane with the major portion or body of the shank, and this extended end portion may receive the blows from a hammer or other tool in order to pitch the blade 2 at a desired angle with relation to the plow body or plate. That is to say, the lug 4 contains approximately just' enough metal to hold the blade in position afterit has been set, and by striking down upon the inner end of the shank 3 the blade may bev turned upon' the bolt 6 and the lug 4 by being brought forcibly against the edge of the cleat 7 is slightly distorted from its original disposition with relation. to the body of the shank 3.

Having thus described the invention, what is claimed as new is:

In combination with a plow body having at its rear side a cleat, a blade having a shank bent at an angle to the blade and with its medial line forming a continuation of the medial line of the blade, a right angled ex- In testimony whereof We afiix our signatension formed at the free end of the shank, 1 tures in presence of two witnesses.
